Topics: Technology : Cryotechnology
This category includes all aspects of Cryogenics: the production and study of extreme sub-zero temperatures. This includes the production, use, and storage of liquid gases (nitrogen, oxygen, helium), mechanical freezers for those temperatures, and the attempts to reach absolute zero. It also includes a recent use of cryogenic technology in which metals are dipped in liquid nitrogen to improve various qualities.
Cryogenic Processing of Materials
Cryogenic Processing of Materials is the technique of immersing materials in liquid nitrogen (at -196 degrees C or -320 degrees F) in order to strengthen them.
